Husking roll



Patented Mar. 22, 1949 UNITED STATES PATENT OFFICE HUSKING ROLL AndrewJ. Garvey, Omaha, Nebr.

Application July 23, 1945, Serial No. 606,686

1 Claim. 1

My invention relates to a husking roll.

An object of my invention is to provide a husking roll which efiicientlygrips the material to be husked from the corn.

A furtherobject of my invention is to provide a husking roll ofresilient gripping material, and to provide in combination therewith, apair of end members having a certain construction to eliminate the endwear of the husking rolls.

A further object of my invention is to provide in such end membersfeatures for preventing the entrance of dirt and other material into theand bearings supporting the roll.

A further object of my invention is to provide a pair of such endmembers which include keying elements so arranged to provide aneflicient gripping effect on the discs making up the roll, and toprovide an installation feature to automatically provide such a result.

A further object of my invention is to provide such end members whichwill maintain a uniform diameter to the roll regardless of the extent ofusage thereof.

With these and other objects in view, my invention consists in theconstruction, arrangement, and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claim, and illustrated in theaccompanying drawings, in which:

Figure l is a plan view taken partially in section of the roll of myconstruction with its companion roll, a

Figure 2 is an enlarged detail section of one of the end members and themembers attached adjacently thereto, and I I Figure 3 is a section takenalong the lines 3-3- of Figure 2.

I have used the character IIIto designate a lengthened shaft, whichshaft receives a plurality of .ring shaped fabric members II, the

' 2| which bearings are suitably bolted either as members I I havingcentral openings for receiving the shaft. Attached at either end of'theshaft III are the special washer members I2. which include an opening'l3for engaging the shaft II). the. members I2 also including thecylindrical annular flanges I4. vPassing through the flange Ilis anopening I5 whichis adapted to freely receive a pin I6; the opening I5-having one side substantially flush with the portion Ilia." Formed Inthe main body ll of the member I2 is a channel or groove I8 which isadapted to.

,receive the cylindrical pin I8 so that one edge of the pin isdirectlyvcoincident with the surface,

I8a', so that the-pin-wIll-not project beyond the 1 at 22 or in anyother customary manner, one end of the shaft at 23 being attached to asuitable sprocket or gear for driving the same. The companion roll orthe roll which frictionally engages the roll II] is indicated by thecharacter 24 and includes the usual ribs 25, etc.

The discs I I are firmly secured in the following manner. One of the endwashers I2 (such as the right hand washer shown in Figure 1) is firstpositioned so that the opening I5 is directly above the cylindrical keyopening 26 of the shaft I0. The key is then dropped through the openingI5 and into the opening 26, and the washer I2 isthen moved outwardlyuntil the key I passes into the receiving groove I8. Next, all of thediscs are assembled on the shaft I0 until the shaft is filled with thesame, and then the other washer I2 is pressed inwardly against theassembled discs in the direction of the arrow 21 (see Figure 2) untilthe opening I5 coincides with the opening 26. The key is then put inplace through the opening I5 and thence is placed into the opening 26.The washer is then allowed to spring back until the groove I8 receivesthe pin I6. The normal resiliency of the discs will permit the aboveoperation and will yet maintain all of the discs in tight engagement.Such discs can be cut from fabric or other stock having similarcharacteristics. The above arrangement is then assembled in its properposition next to its companion roll,.replacing the bearings, etc.

Since the rolls I0 are of a fairly substantial length, and travel at arelatively high speed, the roll usually whips and-bends due to theflexure of the central shaft, and if the end washers [2 were 'notprovided, which washers are made of relatively hard material such assteel or the like.

the ends of the roll would be worn approximately to the'shape'asindicated by the dotted line charor the adjacent roll. During use theprojecting portions of the discs will be worn downto acylindricalsurface as Indicated by the character 29 which surface 'isflush with the peripheral boundaries ofQthe flanges I4. It will be notedThe present structure however. protects that the companion roll 24 bearsagainst the washers at its ends resulting in the efiects abovedescribed. It will be further noted that the method of keying thearrangement efficiently locks the various members, that the washerprotects the bearing, and that the keying method provides an easy methodof assembly. It will be further noted that the special keyingarrangement prevents the key l6 from contacting against the ends of thebearings 20 or 2|, since the key it is recessed beneath the surfaceIlia.

It will now be seen that I have provided all of the advantages mentionedin the objects of my invention with further other advantages beingreadily apparent.

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claim anymodified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.

I claim as my invention:

A husking roll comprising a plurality of fabric within the same forprotecting said bearings, said roll including a shaft upon which saiddiscs and washers are mounted, means for keying said washers to saidshaft, said keying means including pins, depressed channels in saidwashers for receiving said pins, said washers having recessed facesflush with the outer edges of said pins when said pins are placed insaid channels to prevent abutment with the ends of said bearings, saidwashers having annular flanges surrounding said cavities, said flangeshaving openings therein for receiving said pins for assembly thereof tosaid shaft, said shaft having pin receiving openings, said flangeopenings being positioned to one side of said channels whereby pressureof said washers against the resilient fabric discs will providealignment of said flange openings with the shaft pin openings, andwhereby release of pressure of said washers will cause said channels toreceive said pins.
